Detection of wooden foreign bodies within the orbit can be difficult on imaging, including computed tomography (CT). When visible, wood appears iso- or hypodense and can mimic air or fat. We report the case of a 3-year-old boy with progressive orbital cellulitis following a penetrating wood injury to the right lower lid. CT imaging revealed a linear hyperdensity contiguous with an orbital abscess. He underwent a right anterior orbitotomy with abscess drainage, during which exploration revealed a 2.3 cm retained wooden foreign body. The appearance of wood as hyperdense on imaging is unusual. In the appropriate context, high clinical suspicion for retained wood should be maintained with any irregularity on CT imaging.
在包括计算机断层扫描（CT）在内的影像学检查中，检测眼眶内的木质异物可能具有挑战性。当木质异物可见时，其表现为等密度或低密度，可能会被误诊为空气或脂肪。我们报告了一例3岁男孩的病例，该男孩右眼下睑穿透性木质损伤后出现进行性眼眶蜂窝织炎。CT成像显示一条与眼眶脓肿相邻的线性高密度影。他接受了右眼前部眶切开术并进行脓肿引流，术中探查发现一个2.3厘米的残留木质异物。木质异物在影像学上表现为高密度是不常见的。在适当的情况下，对于CT成像上的任何异常，都应高度怀疑有残留木质异物。
